Can't understand who would drop $145 on a night cream? You really won't get it after you try this $16 imitation! Here are the cheapie products that work just as well as their high-end counterparts

We all have that friend who goes to Sephora every day after work, drops by the department store beauty counter during her lunch break, and is the first to know about the newest moisturizer/eye cream/"it" anti-aging product.

For her, the mere thought of buying a drugstore skin care product makes her die a little inside.

Now don't get us wrong, we have nothing against beauty brand junkies. And we're the first to admit that cleansing with Clarins gives us not-so-cheap thrills, too. But what's a beauty editor on a budget to do? Find cheaper alternatives that work just as well as those crazy spendy products, of course.

Here's a little insider secret: While some prestige brands have hefty price tags to cover their high quality ingredients, a good chunk of their production costs go to their fancy-looking packaging. In fact, many brands spend more resources designing the package than creating the formula itself. On the flip side, drugstore brands' bucks go into researching the product formulas -- which means much of what you can buy for $20 or less at CVS is pretty damn similar to what you'll pay $80 and up for at the department store.

That's why we went to skin care expert Paula Begoun, best-selling author of "Don't Go to the Cosmetics Counter Without Me," to find out which drugstore products are truly comparable with high-end faves. Now you too can have flawless skin like your Sephora-obsessed friend -- except with more cash in your pocket to spend at H&M, too.
